Dynkur, also known as Budarhalsfoss or Búðarhálsfoss, is one of the many powerful waterfalls in the river Þjórsá (Thjorsa). In summertime when the snow from the mountains is melting the volume of the river reaches its top with 90-180 m3/sec water that falls down from Dynkur.
Dynkur is a waterfall in the river Þjórsá situated in the south west of Iceland along road 26, near the crossing of road 32. When driving on road 1 in the south near Rangárþing ytra, take the exit road 26 and drive towards Sumarliðabæjarvegur for 62 kilometers. At the crossing with road 32 take the turn to the left (Þjórsárdalsvegur). After 2 kilometers you will cross the river Þjórsá and after another 11,5 kilometers there is an exit to the left, a black sanded road. With a 4WD you can come near Dynkur but this requires some skills and navigation. The last part you have to walk.
Before you reach Dynkur there is another nice waterfall Gljufuleitarfoss.
Along the longest river in Iceland, the river Þjórsá (Thjorsa), lies the Þjórsárdalur valley. In Þjórsárdalur you will find many of the finest waterfalls of Iceland and on a clear day you will have a view on the most famous volcano of Iceland, Hekla. There are about 20 ruins of farmhouses of the time of the big eruption of Hekla in the year 1104. A flourishing farming community lived in Þjórsárdalur after the settlement.
Nearby you will find Haifoss (122 m): one of the highest waterfalls in Iceland, Gjain: a small but really scenic waterfall or Hjálparfoss: famous because of the basalt rocks. We only visited Hjalparfoss because this one was easy to reach. We tried to drive to Gjain but with a small 2WD that was impossible to do. A shame because Gjain and Haifoss are in my top 10 of most beautiful waterfalls in Iceland.
